Dimensional models are intended to reflect what constitutes personality disorder symptomology according to a spectrum, rather than in a dichotomous way.As a result of this they have been used in three key ways; firstly to try to generate more accurate clinical diagnoses, secondly to develop more effective treatments and thirdly to determine the underlying etiology of disorders.
The three main approaches have been labelled as 'quasi-dimensional', 'dimensional' and 'fully dimensional'. [10] Each approach is sometimes used to imply that schizotypy reflects a cognitive or biological vulnerability to psychosis, although this may remain dormant and never express itself, unless triggered by appropriate environmental events ...

[14] Dimensions are defined as continua that reflect individual differences in a maladaptive characteristic across the entire population (e.g., social anxiety is a dimension that ranges from comfortable social interactions to distress in nearly all social ...

For example, raised levels of dopamine may be a consequence rather than a cause of schizophrenia. Many psychologists criticise psychiatry for focusing its attention primarily on symptoms and for assuming that relieving symptoms with drugs cures the problem. Unfortunately, in many cases when the drug treatment is ceased the symptoms recur.
